PLEASEEEEEEEE HELP
Rama09 [41]

Answer:

Using the point-slope form:

The equation of the line is given by:

y-y_1 =m(x-x_1) .....[1]  where

m is the slope of the line and (x_1, y_1) is the point on the line.

As per the statement:

Given: Two points i,e (34, 76) and (42, 91)

First calculate slope(m):

Slope is given by:

\text{Slope} = \frac{y_2-y_1}{x_2-x_1}

Substitute the given values we have;

\text{Slope (m)} = \frac{91-76}{42-34}=\frac{15}{8}=1.875

Now, substitute the value of m and (34, 76) in [1] we have;

y-76 =1.875(x-34)

Using distributive property: a \cdot (b+c) = a\cdot b+ a\cdot c

y-76 =1.875x-63.75

Add 76 to both sides we get;

y=1.875x+76

Therefore, the equation of the trend line is: y=1.875x+76
